Femoral condyles
Quick answer
The femoral condyles are the two rounded knuckles at the lower end of the thigh bone, one on the inner (medial) side and one on the outer (lateral) side. Covered in cartilage, they roll and glide on the tibia as the knee bends, says Dr. Pablo Gelber, a knee surgeon practising at Aman Hospital in Doha.
What they are
Each condyle is a curved, cartilage-covered surface that rests on a meniscus and the matching half of the tibial plateau. The medial condyle is larger and carries more of the load in most people, especially those who are slightly bow-legged. The space between the condyles at the back, the intercondylar notch, holds the anterior and posterior cruciate ligaments.
Why they matter for patients
The condyles are where many cartilage problems are found. A twisting injury, such as an ACL tear in football or padel, can bruise the bone of the lateral condyle or knock off a piece of cartilage. In children and teenagers, osteochondritis dissecans usually affects the medial condyle, where a fragment of bone and cartilage loosens. In knee osteoarthritis, the medial condyle often wears first.
The size, depth and location of a condyle defect help decide treatment, from physiotherapy and load management to arthroscopic repair or cartilage restoration techniques.
How they are examined
Standing X-rays show narrowing of the joint space over a worn condyle. MRI is the main test for cartilage injury, bone bruising and osteochondritis dissecans, and arthroscopy allows a direct look when surgery is already planned.
Frequently asked questions
What does a lesion on the femoral condyle mean?
It means an area of damaged cartilage or bone on the condyle. Its importance depends on its size, depth, stability and your symptoms, which a surgeon assesses with examination and MRI.
Can damage to a condyle heal on its own?
Bone bruises usually settle over weeks to months. Cartilage has a poor blood supply and heals poorly, so larger defects may need treatment if they cause pain, swelling or catching.
